My Emanage Ultimate experience, 5sfte + emanage ultimate = ??? lets find out! Options

[presure2]

Hey all,
So, I've finally made my decision about what to do with the 5sfte, and ways to improve it, and as we all know one of the main areas that we're lacking is tuning, or lack there of, I should say! haha..
Anyway, I've been doing some research on the various piggybacks out there, and I've decided to go ahead and try the Greddy Emanage Ultimate.
I'm gonna try and make this thread somewhat like my turbo thread, with lots of pictures and info, spread out over the whole experience from beginning to end.
So, with that in mind, let me just go over a few things before I really start in with the 'Ultimate stuff.
For those who havent seen the thread yet, or are new to the board, heres a link to my turbo thread.
Click for my 5SFTE post
That pretty much covers my particular setup, and what I've done with it to date.
Just for the record, the car is driven daily, and NOT babied at all.
That being said, as crazy as it may sound, I really DO believe there is more in it, and fairly reliably as well.
Since the install last June, I've learned tons about how this thing we call the 5SFTE really works, why it does what it does, and I'm still learning tons and tons more about it everyday.
I really cannot stress how important it is to try and learn as much as possible about your particular setup, what does and doesnt work, and why it does what it does.
I think one of the main issues we need to look at is how the stock N/A ECU applies timing VS' say a stock 3SGTE ecu, which is one of our big hurdles when it comes to tuning, and IMO one of the main reasons alot of guys loose the 5sfte battle...lol
I've noticed during my dyno runs, when i had the BTM installed, that the ECU REALLY seemed to be pulling ALOT of timing, right at 4450RPM, as you can see in this dyno run:

At first i thought it may have somthing to do with the BTM, so I played with it some, and it seemed the more I turned it down, the less it seemed to pull back, so I finally got to the point where it was totally @ 0, and I removed it.
Although i could still feel it pulling timing, it was ALOT better without the BTM, and here is my theory why: (this is JUST A THEORY, I AM NOT SAYING THIS IS WITHOUT A DOUBT WHATS HAPPENING, keep that in mind.
the factory ECU has timing maps that are set for N/A operation. at the torque peak, there is just too much timing in the factory map for the amount of boost im trying to run, on pump gas. by the time the ecu reacts, im hitting the knock sensor, causing the ecu to pull out timing, and that coupled with the timing already being pulled by the BTM ( im WAY into full boost by then..lol) just makes the whole thing worse.
I really think that with the features of the Emanage ultimate, I'll be able to totally solve that issue, and really improve my tune all around.
First thing I've done, is head right over to www.greddy.com , and downloaded the installation and operation manuals from there.
Once I did a little reading, I noticed some really cool features that I thing will REALLY help us get a MUCH improved tune on our 5SFTE's.
heres a screenshot of some of the features it has:



cool stuff.
I'll keep updating this post over the next couple of days with lots more info and stuff..
for now,
DISCUSS!!

Hey Manny, Can the ultimate lock the timing so that the advance can be totally user controlled... otherwise it seems like since it's altering the MAP signal every time you lower a value in the fuel map you'd have to change it in the timing map as well in order to compensate for more advance due to lower load. Does this make sense or am I confused about how the emanage works?

you dont have to use the map sensor to control fuel.
the emanage ultimate intercepts the injector signals themselves, independant of timing.

you CAN use it in the way you discribe, without the timing lock.
im still struggling trying to get the emanage ultimate to read my timing signals properly.
i have alltracman78 coming down to mess with it with me in a couple weeks.
for now, im still learning this thing, and figuring out what it can do.
one of the downsides of not fully knowing what im doing, and not having the money to just have it tuned professionally.
i think the OBDII guys will have more luck with the emanage ultimate, since they have the crank sensor, which the 94-5 do not.
